The State of Washington has designated the highway between,
Clarkston and Ilwaco,
an official Lewis and Clark Trail Highway. Markers, as adopted by the Federal Lewis
and Clark Trail Commission, have been erected intermittently along the entire route by the
Washington State Department of Transportation.

Part of the "Trail Highway" includes the
Columbia River Gorge National Scenic Area, which slices 80 miles through the Cascade
Mountains.

down river to view potential rapids, 1805.

Stard. Side near the lower point of this island on the Stard. Side about 800 feet high and
400 paces around, we call the Beaten rock"

Lewis remarks about "Beacon Rock" proceeding up the
Columbia in 1806.

" this remarkable rock which stands on the North
shore of the river is unconnected with the hills and rises to the hight
of seven hundred feet; it has some pine or reather fir timber on it's
northern side, the southern is a precipice of it's whole hight. it
rises to a very sharp point and is visible for 20 miles below the river"
